3.1 EVDR for road vehicle accidents system that stores vehicle video data of the accident on an electronic recording medium before, during, and after collision accident events with other vehicles, with passers-by and with any other objects.
3.2 event data information recorded by the EVDR to facilitate analysis of accident scenarios in the case of collision accident events with other vehicles, pedestrians or objects.
5 Types of EVDR
5.1 Classification by security level
EVDRs can be classified into two types listed below depending on the security level.
1) General type: EVDR without video-data integrity-checking function for stored event data.
2) Enhanced security type: EVOR equipped with video-data integrity verification function for stored event data.
5.2 Classification by interoperability of functions
EVDRS can be classified into two types listed below depending on interoperability with DTG or EDR.
1) Independent: EVDRS that operate independently from DTGs or EDRs.
2) lnterlinked: EVORs that operate interlinked to DTGs or EDRs.
6 Functional requirements
6.1 Basic functions of the EVDR for road vehicle accidents The primary purpose of EVDRs is to record video data before, during and after the event. For
EVDR systems, the direct connection to the vehicle’s internal signal line such as the in-vehicle network (IVN) or the analogue signal line is not required. Only the power line of the EVDR is connected to the power line of the installed vehicle.
The EVDR shall have the following basic functions.
a) Input interface function that accepts input from the video acquisition device and the GNSS receiver; the GNSS receiver and/or video acquisition device can be either included in or separated from the EVDR main system (see Figure 2).
b) Decision-making function to check the accident event: the EVDR checks if an accident event has occurred based on the vector sum of acceleration in the XA and X directions, expressed as a, and a. or based on the difference of acceleration per unit of time. For interlinked EVDR systems. the decision-making function to check the accident event can be located in the interlinked DTG or EDR
c) Recording and maintaining functions for event video data:
1) general type: safely records and maintains event video data;
2) enhanced security type: safely records and maintains event video data while preventing doctoring and deletion of the event data.
d) Output interface function to transmit stored event video data: the DTG or EDR of the
interlinked EVDR system can have the following functions. Since the interoperability
function is enabled, the same functions are not required to be included in the EVOR:
1) accident event decision making function:
2) event data recording function;
3) event data storing function;
4) sensor function including GNSS for acquisition of event data.IEC 63005-1 pdf download.
